Abstract

The invention relates to an anticorrosion coating for oil pipelines, which is prepared from the following raw materials in parts by weight: 1.2-2.5 parts of wax powder, 2-4 parts of polytetrafluoroethylene, 3-6 parts of sodium methylene bis-naphthalene sulfonate, 4-9 parts of iron whiting, 7-16 parts of barite powder, 1-3 parts of antioxidant, 1.2-2.6 parts of water-based defoaming agent, 4-7 parts of color master batch, 0.3-0.6 part of nano silver, 7-15 parts of lignocellulose, 2-4 parts of lubricant, 5-8 parts of sodium methacrylate, 2.5-3.2 parts of rutile titanium white, 20-35 parts of water-based elastic acrylic emulsion and 0.6-1.3 parts of sodium borate. The anticorrosion metal surface coating can well adhere to the pipeline surface, thereby reducing the contact with the outside, postponing the corrosion of the pipeline and prolonging the service life of the pipeline.

Description

technical field [0001] The invention relates to an anti-corrosion coating for oil pipelines. Background technique [0002] Coating refers to a thin layer of material that adheres to a certain base material and plays a special role, and has a certain bonding strength with the base material, and has a good protective effect on the base layer. Because the transported oil contains sulfur and acidic substances, and the pipeline is exposed to wind and rain in the open air, the pipeline is easily corroded. Pipeline corrosion mainly includes the following types: oxygen absorption corrosion of steel caused by the principle of primary batteries; hydrogen evolution corrosion caused by extremely acidic sulfides (sulfur dioxide and hydrogen sulfide) on the surface of pipelines due to acid rain; carbon dioxide acid corrosion caused by atmospheric precipitation ; Bacterial corrosion caused by bacteria that can metabolize sulfate on the surface of the pipeline and corrosion caused by water...
